One of the key problems with ChatGPT right now is the limit on how long your conversations can be. ChatGPT can only support about 10 pages of text. But we all have documents way longer than that.

What to do?

While not a perfect solution, this category of tools reads PDFs of any length (even 1000s of pages). You ask a question, the tool picks out the sections it thinks are the most relevant, then gives it to an AI model like ChatGPT.

Note: This means you can't ask any questions that have to deal with the entire document at once. We expect chatbots like ChatGPT to be able to handle longer documents, which would render this category unneeded.
